Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624812, here are decompositions:

5 + 8624807 = 8624812
41 + 8624771 = 8624812
59 + 8624753 = 8624812
179 + 8624633 = 8624812
191 + 8624621 = 8624812
239 + 8624573 = 8624812
353 + 8624459 = 8624812
419 + 8624393 = 8624812

Showing the first eight; more decompositions exist.
